Markdown block writer

Generate a Markdown file by appending text blocks one after the other. The optional header is written once at the top of the file, the separator is inserted between every pair of consecutive blocks (never before the first block or after the last one), and the optional footer is written once at the bottom of the file.

Example
// 1st input: "# Chapter 1\nOnce upon a time..."
// 2nd input: "# Chapter 2\nThe end."

// Configuration:
// Header:    "# My book\n"
// Separator: "\n---\n"
// Footer:    "\n(c) 2026"

// Output file:
# My book
# Chapter 1
Once upon a time...
---
# Chapter 2
The end.
(c) 2026
